Constructor not being called.

When I call my constructor, nothing seems to happen :( I'm getting this error message:

warning C4930: 'String something(void)': prototyped function not called (was a variable definition intended?)

Heres what I have so far of my class:

Code:

---

typedef unsigned char Uint8;
typedef unsigned short Uint16;
typedef unsigned int Uint32;

class String
{       
        public:
                String();
                String(const char *);
                ~String();
                int Len(char *str);
                void StrCat(char *str, char *add);
                void PrintString();
                void SetString(char *str);
               
        private:
                Uint16 size;
                char *str_ptr;
};

String::String()
{
        size = 1;
        str_ptr = new char[size];
        *str_ptr = '\0';
        cout << size << "\nSay something!";
}

---

And heres where I'm making a new string object:

Code:

---

int _tmain(int argc, _TCHAR* argv[])
{
        String something();
        return 0;
}

---

Can someone tell me why nothing seems to happen? I'm sure it must be something really simple. Cheers.

That's not an object being default constructed, that's a function prototype.

I originally did it without the brackets, but then I got this error:
fatal error LNK1120: 1 unresolved externals
Which made even less sense to me :confused: I had a play around with it today, and I found that I needed to put a couple of braces after my destructor. So yeah, it works now thanks :)

Perhaps that is because you told the build chain that you were going to write a destructor, among other functions:

Code:

---

                ~String();

---

But you never actually provided them like you promised.

yeah, that would be it. I'll learn to understand the error messages someday ;)
